In order to maintain the functional capability of a process computer system used in nuclear power plant, it is necessary to keep both structural integrity and information processing function during design earthquake.Based on failure mode analysis of the process computer system against the earthquake, a method of evaluating functional capability of process computer system is proposed. In this method, the acceleration responses of computer equipment are calculated by FEM and compared with the allowable accelerations obtained by the seismic proving test. The proposed method is examined its usefulness in evaluating the functional capability of an actual process computer system in a nuclear power plant and its validity is verified.
